Background
The chronic hyperglycemia of diabetes mellitus is associated with long term damage, dysfunction and failure of various organs especially the eyes, kidneys, nerves, heart, and blood vessels. Electrocardiographic (ECG) abnormalities are found to be predictors of silent ischemia in asymptomatic persons.
Aim and Objective of the study
The purpose of this study is, to detect & compare the electrocardiographic changes (QRS complex) in asymptomatic type II diabetics & controls.
Materials and Method
Fifty type II DM cases aged between 30–55 years and minimum of fifty age and sex matched controls for each group were selected from the general population satisfying the inclusion criteria.
Findings
There was statistically highly significant increase in QRS duration among type II Diabetics when compared to controls (p< 0.001). There was no statistically significant difference in QRS axis between type II DM cases and controls (P > 0.05). There was no statistically significant difference in QRS amplitude among type II diabetics when compared to controls (p > 0.05).
Conclusion
The prolonged QRS complex can be considered as the evidence that the heart of diabetic patients is damaged by cardiomyopathy. Hence the screening of diabetics for electrocardiographic abnormalities is strongly recommended at the time of diagnosis for proper interventions & to prevent complications at the earliest.
